ROAD MAKING AND"TREATING APPARATUS Filed April 1, 1938 Patented Nov. 4, 1941 UNITED STATES PATENT OFFICE ROAD MAKING AND TREATING APPARATUS Frank L. Carswell, Kansas City, Mo. 7 Application April 1, 1938, Serial No. 199,463

2 Claims (01. 299-34) My invention relates to a road oiling machine, and has for its principal object to providea machine of that character which may be selectively employed for working a roadway, or for merely oiling the surface of the road, thereby-effecting a saving in cost of equipment and storage space to contractors or counties or other political units engaging in road construction and maintenance.

In accomplishing this and other objects of my invention I may employ road working machanism of known type, such as the suboiling mechanism disclosed in my Patent No. 2,138,904 of December 6, 1938, but prefer to associate therewith an improved oil spraying unit, which, with the coupling of such unit to the road working elements, constitute the present invention.

In accomplishing the stated objects of my invention I have provided improved details of structure, the preferred form of which is illustrated in the accompanying drawing, wherein:

Fig. 1 is a side elevation of the oiling. mechanism, with the left rear truck wheels and mud guard removed for better illustration.

Fig. 2 is a plan view of the oiling mechanism.

Fig. 3 is a detail perspective view of parts of the oiling mechanism particularly illustrating adjustable support of the oil distributing lines.

Referring more in detail to the drawing:

I designates a main frame of the type employed in connection with road working mechanism, including an overhead frame 2 supported at its forward end as in conventional practice, whereby the combined machine may be connected with a tractor or the like. At its rear the frame 2 extends downwardly to connection with the sills 8 carried by the rear truck indicated at 9 and having a cross sill I!) at their rear ends, presently described.

Leading from the discharge end of the pump (not shown) is a flexible line I! adapted for selective connection to a, pipe 2| for supplying oil to the oiling mechanism at the rear of the machine. As the road working and oiling are performed separately and not simultaneously, the single connecting line will serve for conducting oil from the pump to either of the mechanisms. The pump may be operated by an engine which with the pump is preferably mounted on the rear frame sills and having the intake connected with an oil supply tank as in conventional practice.

Referring now to the oiling mechanism, 23 designates a forward extension on the pipe 2|, turned laterally as indicated at 24 (Fig. 2) to form a manifold section 25. Connected with the manifold 25 through T fittings 26 are the rearwardly extending branch lines 29-30.- Connected with the rear ends of the branch pipes by L fittings 3| and 32 andextension pipes .33 and 34 are distributor pipes 3536jclosed at their respective ends by caps 31-38 and provided with downwardly extending nozzles 39, the adjacentinner ends of the distributing sections'being coupled together by a plate 40 and U-bolts 4|. Supply. of oil to the distributing pipes 35 and 36 is'controlled by valves 43-44 preferably arranged tobe actuated simultaneously by levers 45 and 46 connected by a link 41, or individually upon disconnection of the levers from said link. The link 41 is connected with one arm 48 of a bell crank lever 49, preferably mounted on the fitting 25 of the inlet connection. The other arm 50 of the bell crank lever is provided with a link 5| which leads to the lower end of a control element 52, and is connected theretoby an arm 53, Fig. 2,. the control element being provided with a suitablehandle 54 arranged inconvenient position relative to the engine, to facilitate operation of the apparatus by a minimum number of operators.

In addition to control of quantity of fluid with which a road surface is treated, it is desirable to sometimes control the direction of the spray. For example, when one part of the road has been prepared, as by scarification, and the other part is unprepared, the prepared part of the road should be sprayed uniformly and it would serve no purpose to spray the unprepared part of the road.

In order to limit application of the spray to that portion of the road desired to be sprayed, I adapt the spray members for swinging movement relative to their supporting frame. This is accomplished by interposing swing joints 56 and 51 between the spray members and the inlet connection, the swing joints preferably being mounted at the ends of the fluid delivery members 29 and 30 adjacent the valves 43 and 44 in such a manner that an adequate swinging movement of i the spray members is permitted.

It is apparent that substantially a uniform motion is provided for the spray members and in order to facilitate control of such movement, I provide brackets 58 and 59, Fig. 3, which are preferably of substantially rectangular shape and have upwardly extending flanges and BI at their upper ends. The brackets 58 and 59 are preferably connected to the rear sill ID of the sills 8 by the flanges 60 and BI to adapt the spray members for vertical adjustment relative to the sills 8 and the surface of a road over which the apparatus is being drawn. The members 68 and BI preferably consist of plates having spaced aligned perforations 65 adapted to receive bolts 66 extending through a web 61 on the rear sill H] of the frame. Spacing members 68 carried on the bolts engage the web of the cross sill Ill between the upper and lower flanges of the sill I8 to assist in fixing the brackets 58 and 58 in desired vertically adjusted position.

In order to move the spray members laterally, ears 10 and H are mounted on the outer sides and near the outer ends of the fluid delivery members 29 and 30, respectively, and connected with the ends 12 and 13 of a cable 14 or the like, run over guide sheave wheels 15 fixed, as by brackets 16, substantially at the outer forward faces of the rear sill 10, over pulleys H and 18 on brackets 19 on the side sills of the apparatus frame, and around the lower end 80 of a control element 8|, such as shown in Fig. 1. The control element BI is preferably positioned adjacent the control element 52 and provided with a hand wheel 82 for winding the cable on the lower end of the element 8| in either direction to swing laterally relative to the frame in either lateral direction.

In order to spray portions of the road that are inaccessible to the spray on the machine, a hand hose 83 is connected to the T fitting 26. A valve 84 is provided adjacent the T for controlling flow of fluid from the hand hose. Under normal conditions the valves 43 and 44 would be closed when valve 84 is opened and valve 84 closed when valves 43 and 44 are opened.

When the machine is to be used as a surface oiler, the pump may be connected with the pipe 2| leading to the spray pipes, and the oil supply line to the tank at the rear of the machine.

With the machine traveling along the roadway and the pump in operation oil is forced through the oiling mechanism to be distributed on the road surface from but one of the spray pipes if a narrow oiling width is desired, or from both if a wide spray is desired, the elevation and angle of discharge of the spray pipes being selectively controlled as previously described.

A machine constructed as described is available for the work ordinarily performed with separate road working and road oiling machines at a considerable saving over the cost of separate machines for performing the different operations, either type of working being accomplished as effectively with the combined machine as with a machine adapted only for a specific purpose, a saving in storage space and labor being also effected by combination of the two machines in one.

What I claim and desire to secure by Letters Patent is:

1. In a road oiling mechanism, a frame, a fluid supply manifold mounted on the frame, branch lines leading from the manifold, horizontally arranged distributing pipes connected with the respective branch lines and mechanically connected to move as a unit, flexible joints in the branch lines, valves in the branch lines, guide members on the frame arranged laterally of the branch lines on opposite sides thereof, flexible lines engaged with the pipes respectively and passing over said guide members, and a control member connected with said lines and adapted to move the same in opposite directions to adjust said pipes laterally relative to said frame.

2. In a road oiling mechanism, a frame, a fluid supply manifold mounted on the frame, a branch line leading from the manifold, a distributing pipe connected with the branch line, a flexible joint in the branch line, a bracket on the frame supporting the branch line delimiting lateral movements of said line while supported by said bracket, and means on the bracket vertically ad- 40 justably connected with the frame to adjust the line vertically relative to the frame.
